摘要
生态足迹是一种定量评价区域资源可持续利用的生态经济指标,其方法紧扣可持续发展的理论,是一个涉及系统性、公平性和延续性的综合指标,具有可度量性、计算合理性和结果可比性等优点。在介绍其概念、计算模型的基础上,针对中国中部六省的资源和能源消费状况进行了实证分析。研究表明:本区2004年人均生态足迹1.793hm2,生态承载力为0.488hm2·人-1,生态足迹需求与供给的比例为3.677∶1,人均生态赤字为1.305hm2,说明中部地区的发展已经超出了生态承载力的阈值;该区生态足迹多样性指数1.336,万元GDP足迹1.982hm2,生态协调系数1.227等,也反映了中部地区处于一种不可持续的发展状态。
Ecological footprint closely relating to sustainable development theory is an ecological and economic index which can reflect the sustainable development level of a country or region quantitatively, and is a synthetic index relating to systemic, fairness, and sustainability which have many merits such as measurable consumption, rationality, and comparison et. Based on the concept of ecological footprint and its computer models, the paper analyzed the energy and resources consumption of Middle China. The calculation results showed that the per capita ecological footprint was 1.793 hm^2, the ecological capacity 0.488 hm^2 and the ecological deficit 1.305 hm^2 in 2004, the ratio of ecological footprint＇s demand and supply was 3.677 ： 1 ; The ecological footprint＇s diversity is 1.336, the ecological footprint per unit of GDP is 1.982 hm^2, and the ecological coordination quotiety is 1.227 et. As a result, it is considered that the ecological footprint is beyond the ecological capacity, regional development is unsustainable.
